Contestor D-60 sideport ignition engine. Used but in super condition as I have bench tested it. Rings look like new with great compression. timer arm has a removable extension . Extra timer parts included. 4- page copy of original instructions and Charlie Bruce's Old engine analysis of the engine included. These D-60-S engines were made in very small numbers and ran better than the D-60R because of Dan Bunch design of the "tuned pipe effect of the side port" . $190.00 and Shipping Priority $17.05
